DISHWASHING APPARATUS.

Original 110. 1,330,734, dated Augiut 9, 1921, Serial No. 418,887, filedOctober 23, 1920. Application for reluue filed January 28, 1922. SerialNo. 532,510.

To allwlwmit may concern."

Be it known that I, HARRY ROSENBAUM, citizen of the United States,residing at New York, in the county of New York and State I of New York,have invented new and useful Improvements in Dishwashing Apparatus,

of which the following is a specification.

This invention relates to apparatus for washing dishes, and moreparticularly one inwhichthe dishes'are placed in a closed stationaryreceptacle and subjected to the cleansing action of a plurality ofstreams of water sprayedover the same.

The invention has for its object to provide- Referring specifically tothe drawing, 5

:0 denotes a water-tight receptacle of any suitable contour anddimension, in which the dishes to be washed are placed, access to thereceptacle being had by having the same open at the top. A tight fittinghinged door 6 is provided for the top of the receptacle, and in thereceptacle are mounted suitable racks 7 which support the dishes shownat 8.

Passing centrally through the receptacle 5 is a rotatable spray pipe 9which is providedwith a large number of perforations 10 through with thewater is discharged. One

end of the pipe 9 is closed and this end is supported in a bearing 11mounted on the corresponding end wall of the receptacle 5. The other endof the pipe 5 is open and is supported in a bearing 12' mounted on thecorresponding end wall of the receptacle. Thev bearing 12 has a nipple13 which passes through the end wall ofthe receptacle, and on theoutside of the receptacle there is coupled to the nipple a water supplyhose 14 obtaining hot water from any suitable source. The bore of thenipple 13 is in communica: tion with the. open end of the pipe 9, andhence, when the water is turned on, it flows longitudinal section i intosaid pipe and is sprayed through perforations 10 thereof over the dishes8.

One end. of the pipe 9 is fitted with two diametrically'opposite, andradially extending discharge tubes 15 from which the water is dischargedat their outer ends, said ends being bent laterally to obtain atangential discharge. The reaction of the water discharged frolntheftub'es 15 at the outer endsthereof causes said arms to revolve andthus rotate the pipe 9, with the result that the water discharging fromthe perforations 10 is continually sprayed over the dishes 8, and thelatter are rapidly and thoroughly cleansed. The receptacle is providedwith a drain 16.

The apparatus is very simple and efficient, and it is well adapted fordomestic use as it can be operated by connecting the hose 14 .to the hotwater faucet in the kitchen. The

apparatus is also economical in operation as the amount of water itrequires is not greater than that ordinarily used when washing andrinsing dishes by hand.

I claim:

1. A dish washer comprising, in combina tion, a dish receptacle, a spraydevice mounted to rotate upon a horizontal axis within said receptacleand adapted to direct the spray in directions generally transverse tosaid axis, said spra device being provided with reaction jets orcontinuous complete rotation of the same whereby the spray is caused tosweep in continuous complete circles about the axis of rotation of saidspraydevice, and a liquid supply connection for said spray device. 1

2. A dish washer comprising, 'in combina-- tion, a walled dishreceptacle, a spray device extending horizontally between and rotatablysupported by opposite walls of said receptacle, said spra' device beingprovided with reaction jets or continuous complete rotation of the samewhereby said spray is caused to sweep in continuous complete circlesabout said axis, and a liquid supply connection for said spray device.

3. .A dish washer comprising, in combination, a dish receptacle, a.spray device mounted to rotate upon a'horizontal axis .within saidreceptacle and adapted to direct the spray in directions generallytransverse to said axis. said spray device being provided with reactionjets for continuous complete rotation of the same whereby said spray iscaused to sweep in continuous complete circles about said axis, a liquidsupply connection for said spray device and dishsupportingmeans arrangedin said receptacle about said spray device.

4. A dish washer comprising, in combination, a walled receptacle, acentrally located spray device supported by opposite walls of saidreceptacle to rotate upon a horizontal axis within the same, said spraydevice being provided with reaction jets for continuous completerotation of the same whereby the spray is caused to sweep in continuouscomplete circles about said axis, a liquid supply connection for saidspray device and dish-supporting means arranged above and below saidspray device.

5. A washing apparatus comprising a re ceptacle, a perforated spray pipemounted to extend horizontally of the receptacle and to rotate upon itsaxis said spray pipe being provided with reaction jets for continuouscomplete rotation of the same whereby the spray device is caused tosweep in continuous complete circles about said axis, and

dish supporting means arranged to support dishes about said spray pipe.

6. A washing,apparatus comprising a receptable, a perforated spray pipeextending horizontally and centrally between the opposite end wallsmfthe receptacle and rotatably same.

In testimony whereof I afiix my signature.

HARRY ROSENBAUM.
